Struct aws_sdk_appsync::types::SyncConfig

#[non_exhaustive]
pub struct SyncConfig {
    pub conflict_handler: Option<ConflictHandlerType>,
    pub conflict_detection: Option<ConflictDetectionType>,
    pub lambda_conflict_handler_config: Option<LambdaConflictHandlerConfig>,
}

Describes a Sync configuration for a resolver.

Specifies which Conflict Detection strategy and Resolution strategy to use when the resolver is invoked.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

conflict_handler: Option<ConflictHandlerType>

The Conflict Resolution strategy to perform in the event of a conflict.

• OPTIMISTIC_CONCURRENCY: Resolve conflicts by rejecting mutations when versions don't match the latest version at the server.

• AUTOMERGE: Resolve conflicts with the Automerge conflict resolution strategy.

• LAMBDA: Resolve conflicts with an Lambda function supplied in the LambdaConflictHandlerConfig.

conflict_detection: Option<ConflictDetectionType>

The Conflict Detection strategy to use.

• VERSION: Detect conflicts based on object versions for this resolver.

• NONE: Do not detect conflicts when invoking this resolver.

lambda_conflict_handler_config: Option<LambdaConflictHandlerConfig>

The LambdaConflictHandlerConfig when configuring LAMBDA as the Conflict Handler.

Implementations

impl SyncConfig

pub fn conflict_handler(&self) -> Option<&ConflictHandlerType>

The Conflict Resolution strategy to perform in the event of a conflict.

• OPTIMISTIC_CONCURRENCY: Resolve conflicts by rejecting mutations when versions don't match the latest version at the server.

• AUTOMERGE: Resolve conflicts with the Automerge conflict resolution strategy.

• LAMBDA: Resolve conflicts with an Lambda function supplied in the LambdaConflictHandlerConfig.

pub fn conflict_detection(&self) -> Option<&ConflictDetectionType>

The Conflict Detection strategy to use.

• VERSION: Detect conflicts based on object versions for this resolver.

• NONE: Do not detect conflicts when invoking this resolver.

pub fn lambda_conflict_handler_config( &self ) -> Option<&LambdaConflictHandlerConfig>

The LambdaConflictHandlerConfig when configuring LAMBDA as the Conflict Handler.

impl SyncConfig

pub fn builder() -> SyncConfigBuilder

Creates a new builder-style object to manufacture SyncConfig.

Trait Implementations

impl Clone for SyncConfig

fn clone(&self) -> SyncConfig

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for SyncConfig

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for SyncConfig

fn eq(&self, other: &SyncConfig) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
